Taking sharper aim at pesky stomach ulcer bacteria

 What’s inside of one-sixth of the world’s population and is a thousand times smaller than the head of a pin? It’s Helicobacter pylori, the pesky bacterium behind ulcers and other unpleasant stomach diseases. In our latest episode, find out more about H. pylori, and how a scientist from Spain named Javier Sancho may have a new way to fight this common microbe.

Festive Science: A Holiday Chem Lab

What makes the snowflakes flutter down almost hypnotically when you shake a snow globe?

Our new video answers that question and other holiday chem queries in high-definition detail. Check it out!

Festive Science! A Holiday Chem Lab from ACS Pressroom on Vimeo.

The video features Diane Bunce, Ph.D., and her students, who perform experiments with a holiday theme.  Bunce, professor of chemistry at CUA, is a recipient of the ACS Helen Free Award for Public Outreach.

Using the magic of chemistry, the video shows students how to make:
•    A colorful, bouncing super ball made with polymers.
•    A snow globe-like stick, consisting of a test tube filled with water, glitter and glycerine. The glycerine slows the glitter and makes it look like snowflakes falling when the tube is shaken.
•    A marbleized gift card made with shaving cream, paper and various food colorings.

 

Thanksgiving and Chemistry: What's the connection?

Why do people eat mashed potatoes on Thanksgiving Day but not mashed paper towels? That’s not such an odd question from a chemistry standpoint because potato and paper are almost as similar as two peas in a pod in terms of the carbohydrates they contain.

For the answer to that and other topics that could spark dinnertime conversation on Thursday, check out our latest video featuring Diane Bunce, Ph.D., professor of chemistry at Catholic University of America and associate editor for Chemical Education research for ACS’ Journal of Chemical Education.

Thanksgiving and Chemistry: What's the connection? from ACS Pressroom on Vimeo.

The video focuses on traditional Thanksgiving foods, including topics such as:
• How does the pop-up timer in a turkey work?
• Why do muffins rise, even when made without yeast?
• Which antacids neutralize the most stomach acid?
 

 

ChemMatters: Episode 1 - Nanotechnology's Big Impact

The award-winning high school chemistry magazine ChemMatters is making its YouTube debut with its first ever video podcast. The first episode highlights the very big promise of those very small machines known as nanotechnology. The episode explains how incredibly small nanostructures like buckyballs could lead to tiny devices that bring medicine exactly where it needs to go in your body, as well as powerful computers the size of a grain of sand or vital new sources of energy.

PeriodicTableBday.jpg

 

 

It’s National Chemistry Week (NCW), and we here at Bytesize Science are celebrating a very special birthday – this week, the periodic table turns 140 years old! The periodic table lists all of the elements, which are like the ingredients that make up everything on Earth and in the universe around us.

To honor this special occasion, all week we’ll be learning about some of the most fascinating elements out there. But first, let’s start with atoms, the tiny building blocks that make up everything in the universe. Listen to our first NCW podcast to find out more!

Super Buoyant: New materials could make a horse float!

Here's a story that might float your boat: Researchers in China are reporting the development of miniature super-bouyant boats that float better than anything else out there. These boats float so well that an ordinary life preserver made from the same material might support a horse without sinking.
